The other handlever, 22, is also pivoted upon.the pin 23 and is adapted to cooperate with the quadrant whose teeth arewide enough to permit the latch 28 of this lever tqapass the latch 26 ofthe otherlever without interference; The foror lower end of the lever 22extends be yond its pivotal point and is shapedto form a hook 29 toengage a chain 30, connected to a raising-rod 31, which is in turnconnected ()bviously when the hand-lever 22 is in its lowered position,as shown, in respect to the left-hand set of raising and loweringmechanism now being particularly referred to, the beam 5, which itcontrols, is in raised position, as shown in the perspective, Fig. 1.The levers 21 and 22 are arranged'to operate independently and also inunison through the medium of the quadrant,with the result that eitherone of the beams 5 or 6, for instance, may be raised or loweredindependently of the other, or if either one of thelevers is operatedwithout disengagement from the quadrant both beams-that is, 'theentiregan .may be simultaneously raised 'or lowered according to thedirection of movement of such levers; The arch 7 cooperates with thebeams 3 and 4 of the right-hand gang and the arch 8 with the beams 5 and6 of the lefthand gang. To properly distance the two gangs withoutinterfering with theirindependent raising and lowering, rods 32 33' areprovided, as seen in Fig. 1, which rods are pivor adjusted over thequadrant entirely independently. The levers pass or swing adjacentopposite sides or faces of I claim frame, cultivator-beams supportedthereby, a hand-lever for each beam, and means common to the levers ofthe beams whereby the manual operation of either one of the hand-leverswill cause a simultaneous lowering or raising of the beams;substantiallyas described.

In orderto supply the desiredor necessary tension upon the movable or rocking quadrant, a' curvedlink 32 is pivoted at its rearward end to the quadrant, while itsadvance of the rockshaft 13 is connected to a chain 33, passing aroundawheel 34. -This chain is connected inturn to a spring 35, secured at oneend to the transverse bar 9 of the machineframe. The position of thisquadrant, as shown by dotted lines in Fig. 5, is the extreme upward one,further movement being limited by the contact of the foot .36, on thecross-bar 12, Figs. 4 and 5. The full lines in Fig. 5 represent thelowered position of the quadrant, the left-hand quadrant, illustrated inthe perspective, Fig. 1. When the quadrant is in its raised position,the pivotal point \of the link 32, the axis of the rock-shaft,"and thepoint of connection of the link and chain are in substantial alinement,and consequently the position of the quadrant, as shown, is maintainedexcept as against positive forceexerted by the levers or either of themthereupon." As shown in the detail vie w, Fig. 6,the latch or dog ofeach hand-lever passes through the lower end of the lever and extendslaterally to engage the teeth of the quadrant which, as hereinbeforestated, are sufficiently wide to arches, respectively,
